Title: Apparatus for detection of coagulation
IPC: G01N11/04
Filed: 1974-02-08
Abstract: 1457575 Coagulation detection ETABS DAILLET SA 8 Feb 1974 [19 Feb 1973] 05969/74 Heading G1B A process for detecting a viscosity increase in a fluid, particularly a fluid having a viscosity which increases when the fluid is moved to and fro, comprises subjecting a sample of the fluid to to-and-fro movement in a tube at least a portion of which is of such an internal cross-section as to slow down or stop the movement of the fluid when in an increased viscosity condition and detecting when  such movement is slowed down or stopped due to a viscosity increase. The fluid is preferably blood plasma, optionally mixed with a coagulation modifier such as thromboplastin. The movement of said fluid may be produced by displacing a volume of gas acting on the fluid and detecting the resulting increase or decrease in pressure in the gas when the fluid movement is slowed down or stopped due to a viscosity increase which will result in volume and pressure changes in the gas, the pressure change being an increase when the viscosity change occurs as the gas is acting to push the fluid or a decrease when it occurs as gas is acting to pull said fluid. The process may be carried out in an apparatus of the type shown in Fig. 1 wherein fluid sample 9 is introduced into tube 2 from cup 1. Tube 2 is removably mounted at the bottom of a pumping device in the form of a syringe 5 provided with a motor-actuated piston 6. Movement of piston 6 will cause the sample to move to and fro about constriction 3 and when clotting occurs Figs. 2 and 3, (not shown), pressure changes in the volume of gas between the sample and piston will cause the mercury levels in the arms of manometer 11 to rise and fall. Movement of mercury in this manner will complete an electrical circuit when the mercury level contacts either of electrical contacts 12 or 13, thus activating a register or alarm means 14. The apparatus may also be provided with a counter 16 which is actuated by motor 7 and, on completion of an electrical circuit as described above, relay 17 is operated and switches off both the motor and  counter; thus the coagulation time can be accurately recorded. The apparatus may also include a turret means Figs. 6-8 (not shown) whereby the turret, provided with three grooves 26, moves sample tubes between three stations; at the first station I, a section of tube is cut from a supply thereof e.g. a plastics coil, at the second station II, the sample tube is charged with fluid and its viscosity increase detected, and at the third station III, the used sample tube is ejected.

Abstract: 681,391. Interferometers. PRECISION MECANIQUE. March 17, 1950 [March 30, 1949; March 6, 1950], No. 6738/50. Class 97 (i). [Also in Group XIX] An interferometer comprises means for mounting a light source so as to direct, through at least one objective, a convergent beam onto a beam-splitter and a first mirror disposed between the source and the beam-splitter to allow the passage of light from the source to the beam-splitter and to receive and reflect light reflected from the latter, the arrangement being such that this first mirror and the beam-splitter are normal to the objective axis and that light passing through the beam-splitter will be reflected by a second mirror (which may be formed by a surface to be examined) disposed on the opposite side of the beam-splitter and on said objective axis, for recombination with the light reflected by the first mirror, thereby to provide interference fringes. The interferometer shown comprises a cylindrical tube 6 which is spring-connected at 24 to a support 20 in a casing 27 housing an electric battery 29 supplying current to a light source S housed with a condenser 26 in a housing 25 projecting laterally from tube 6. In the light path between the eyepiece 8 of the device and an objective 5 is disposed a partial reflector 7, whereby light from source S is directed onto the object P to be examined. The objective 5 is axially adjustable in a member 11, which carries at its lower end a beam-splitter consisting of plane parallel glass plates 1 and 2 with a partially transparent metallic layer therebetween and is connected at 13 to an external collar 12, which is rotatable around tube 6 to adjust the axial position of the member 4. The lower end of the tube 6 is formed as part of a sphere having its centre at O and rests on the upper spherical surface of a base member 15, which is spring connected at 19 to the tube 6 and is apertured at 17 so that the centre O of the concentric spheres of which the contacting surfaces of the tube 6 and member 15 are part, lies in said aperture in the plane of the lower face 16 of member 15. This mounting allows the angle between the objective axis and the surface of an object P under test to be varied. On the same side of the beam-splitter as the objective 5 is placed a plane mirror 4; this mirror is conveniently formed as a metallic deposit on the lower surface of the objective. In use, light from source S passes down the tube 6 and after passing through the objective 5 impinges on the semi-reflecting layer 3 so that part of the light is transmitted to the test object and part is reflected onto mirror 4. Mirror 4 and the test object P return the light to layer 3 so that the beams are recombined and interference fringes are visible in the eyepiece 8. For use in determining refractive index difference between two fluids, two mirrors 4 are provided, one on each side of the beam-. splitter. One fluid is positioned in the space between the upper mirror 4 and the layer 3 and the other fluid below layer 3.

Class 79 (iii) A steering column, which is detachably secured to the vehicle by a surrounding housing, is locked by a bolt which also penetrates the housing, the column or housing also being secured by a retaining pin which is inaccessible when the column is locked and which is disposed at an angle to the bolt whereby the housing cannot be drawn away from the bolt even though its fastening members are undone. Fig. 2 is a vertical axial section of the steering column and Fig. 1 is a transverse section thereof partly on the line AB and partly on CD of Fig. 2. The steering column e containing the steering shaft g is secured to the dashboard a by a housing d and two bolts b. The housing and distance pieces f may be welded to the column e. A pin p secured by nut o to the dashboard, projects through the housing and column with a close fit. The locking bolt k passes through the housing and column and enters a transverse hole i in the steering shaft and is at an angle of about 45 deg. to the pin p. Thus even though the bolts b are removed the housing cannot be withdrawn from the bolt k by attempting to bend the steering column. The housing d may be extended and serve to mount components such as an operating rod q for a dimmer or dipping lights, gear change rod r and hand brake lever s.

Abstract: 1,153,697. Aromatic formaldehyde resins, purification. ESSO RESEARCH & ENG. CO. 12 Feb., 1968, No. 6808/68. Heading B1B. A resin, produced by reacting formaldehyde (or a polymer thereof) with one or more aromatic hydrocarbons in the presence of an acid catalyst, is separated from the crude reaction product by introducing it through line 14 into zone 11 where it is treated with steam, supplied through sparging device 13, so that an aqueous phase and an oil phase are formed; after allowing the two phases to separate, the oil phase is transferred through lines 20 and 22 into distillation column 23 which is maintained under subatmospheric pressure whereby water and formaldehyde, aromatic hydrocarbons, and low molecular weight polymers are removed as overhead and sidestream fractions, and the purified resin is withdrawn as bottoms fraction through line 28. A solution of sodium carbonate may be introduced through line 16 into the crude resin in zone 11 before the steam-sparging operation. Alternatively, water and aromatic hydrocarbons may be introduced through lines 29, 31. The separated oil phase is passed into a second sparging zone 35 and, after steam-treatment and separation, the second oil phase is transferred to the distillation column 23, which is also supplied with sodium carbonate solution. Instead of using column 23, the unreacted formaldehyde and aromatic hydrocarbons, as well as the low molecular weight polymers, may be removed from the oil phase by submitted it, in the form of a film, to vacuum flashing.
